Widely and abundantly expressed antioxidant enzyme
Glutathione peroxidase (GPx) is an important antioxidant enzyme that plays a crucial role in protecting cells from oxidative stress by catalyzing the reduction of hydrogen peroxide and organic peroxides. It utilizes glutathione, a tripeptide composed of glutamine, cysteine, and glycine, as a substrate to carry GPx is part of the body's antioxidant defense system. By reducing oxidative stress, GPx may help prevent the initiation and progression of cancer. Some studies suggest that higher levels of GPx activity are associated with a lower risk of certain cancers.
The tumor microenvironment is often characterized by increased oxidative stress. GPx can influence the behavior of cancer cells and their interactions with surrounding cells. In some cases, cancer cells may upregulate GPx to survive in this oxidative environment, which can contribute to tumor growth and resistance Inhibiting GPx in certain cancer types may sensitize tumor cells to chemotherapy and radiation therapy by increasing oxidative stress.to therapy.

GPX1 is widely expressed in various tissues and is particularly important in maintaining cellular redox balance. GPX1 expression is often elevated in various cancers and is generally associated with poorer prognosis due to its role in protecting cancer cells from oxidative stress and contributing to treatment resistance.

Ischemic stroke is also called brain ischemia and cerebral ischemia. Ischemia is the medical term for "lack of blood supply."
